## Job description

At Fonoa, we are transforming how digital-first companies stay tax compliant. We provide simple and modular API solutions that easily integrate into any existing workflow. Through our technology-first approach, we reduce manual processes, increase compliance and reduce the cost of operations when transacting and scaling internationally. We are solving one of the largest yet unsolved problems in global e-commerce. Our tax automation software enables companies such as Uber, Zoom & [Booking.com](http://Booking.com) to expand their international offerings more quickly and remain tax-compliant.

## Role Description

We're looking for a Staff Product Designer to help shape the future of Fonoa's AI-native Tax Operating System. You'll design new AI-powered products and experiences, simplify complex tax workflows, and help define the future of our platform. You'll join an independent Design organization, working alongside a high-caliber team of designers, product managers, engineers, and tax managers. As one of our senior individual contributors, you'll have the opportunity to shape our products, influence a brand new design system from the ground up, and raise the quality bar across everything we build. This is a hands-on Staff IC role reporting to the Head of Design, with a strong focus on systems thinking, craft, and execution.

## What you'll do

- Shape the next generation of Fonoa. Design new AI-powered products and experiences that become core parts of our Tax Operating System.
- Own products end to end. Lead the design process from problem framing and research through interaction design, visual craft, prototyping, and launch.
- Simplify complexity. Turn sophisticated tax, regulatory, and AI workflows into intuitive experiences that customers trust.
- Think in systems. Design scalable foundations, contribute to our new design system, and create patterns that enable future products.
- Partner across disciplines. Work closely with Product, Engineering, AI, Tax, and User Research to shape product direction, not just execute requirements.
- Raise the quality bar. Champion exceptional craft, attention to detail, and thoughtful execution across everything we build.

## What we're looking for

- Exceptional product craft. You care deeply about interaction design, visual quality, motion, and the details that make products feel effortless.
- Strong systems thinking. You can design both individual experiences and the larger product architecture behind them.
- Experience building design systems. You've created or significantly evolved systems that scale across products and teams.
- Complex product experience. You've designed sophisticated B2B, enterprise, fintech, developer, or infrastructure products where simplifying complexity was central to your work.
- AI curiosity. You're excited about designing AI-native experiences that solve real customer problems, not just adding AI for its own sake.
- A strong portfolio. Your work demonstrates end-to-end ownership, clear thinking, and measurable impact, not just polished visuals.
- Collaborative mindset. You communicate clearly, challenge ideas thoughtfully, and enjoy working closely with cross-functional teams.
